* except.h (current_function_eh_stub_label): Declare.
(current_function_eh_old_stub_label): Declare.
* function.h (struct function): New members eh_stub_label and
eh_old_stub_label.
* except.c (current_function_eh_stub_label): New variable.
(current_function_eh_old_stub_label): New variable.
(init_eh_for_function): Clear them.
(save_eh_status): Save them.
(restore_eh_status): Restore them.
(expand_builtin_eh_stub): Set current_function_eh_stub_label.
(expand_builtin_eh_stub_old): Set current_function_eh_old_stub_label.
* flow.c (find_basic_blocks_1): When handling a REG_LABEL note, don't
make an edge from the block that contains it to the block starting
with the label if this label is one of the eh stub labels.
If eh stub labels exist, show they are reachable from the last block
in the function.
